I am looking to make an announcement to friends that uses more gender-balanced French. I know that hyphens and parentheses are generally used to separate letters that distinguish genders, but sometimes writing adjectives to properly agree with their corresponding noun can be a bit tricky. Given that this isn't standard French, there are not many resources for how to 'properly' write these types of sentences. I am hoping to crowdsource basic strategies that people use.
For example, in my announcement, I would like to clarify that the message is relevant to my friends in Paris, but 'parisiens --> parisiennes' isn't as simple as just adding an 'es'. My best attempt is:
Ami-e-s parisien-ne-s : [nom de l'artiste] viendra à Paris en mars prochain. Y a-t-il quelq'un-e qui veut y aller ?
